Description
Rat EL (Endothelial lipase) ELISA Kit
The Rat EL (Endothelial Lipase) ELISA Kit is a specialized assay designed to quantitatively detect levels of endothelial lipase in various rat biological samples. Endothelial lipase is an important enzyme that plays a critical role in lipid metabolism and vascular biology. It is involved in the regulation of plasma lipoproteins, particularly high-density lipoprotein (HDL) metabolism, and is implicated in the development of atherosclerosis, cardiovascular diseases, and lipid abnormalities. The quantification of endothelial lipase levels using this ELISA kit can provide valuable insights into lipid metabolism, vascular health, and the pathogenesis of cardiovascular disorders.
Monitoring changes in endothelial lipase expression can aid in understanding its role in lipid homeostasis and cardiovascular risk factors. The Rat EL ELISA Kit from Assay Genie offers exceptional sensitivity and specificity, ensuring accurate and reproducible results. Manufactured under strict quality control standards, this kit delivers robust performance and is user-friendly, making it a reliable tool for researchers investigating lipid metabolism, cardiovascular diseases, and vascular function.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat EL. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat EL and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat EL, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat EL. You can calculate the concentration of Rat EL in the samples by comparing the OD of the samples to the standard curve.
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Rat EL were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Rat EL were tested on 3 different plates, 20 replicates in each plate.
